Datadog-Elasticsearch Integration

Elasticsearch

Overview

Stay up-to-date on the health of your Elasticsearch cluster, from its overall status down to JVM heap usage and everything in between. Get notified when you need to revive a replica, add capacity to the cluster, or otherwise tweak its configuration. After doing so, track how your cluster metrics respond.

The Datadog Agent’s Elasticsearch check collects metrics for search and indexing performance, memory usage and garbage collection, node availability, shard statistics, disk space and performance, pending tasks, and many more. The Agent also sends events and service checks for the overall status of your cluster.

Setup

Installation

The Elasticsearch check is packaged with the Datadog Agent, so simply install the Agent on your Elasticsearch nodes, or on some other server if you use a hosted Elasticsearch (e.g. Elastic Cloud).

Configuration

  1. Create a file elastic.yaml in the Datadog Agent’s conf.d directory. See the sample elastic.yaml for all available configuration options:
init_config:

instances:
  - url: http://localhost:9200 # or wherever your cluster API is listening
    cluster_stats: false # set true ONLY if you're not running the check on each cluster node
    pshard_stats: true
    pending_task_stats: true

If you’re collecting Elasticsearch metrics from just one Datadog Agent running outside the cluster — e.g. if you use a hosted Elasticsearch — set cluster_stats to true.

See the sample elastic.yaml for all available configuration options, including those for authentication to and SSL verification of your cluster’s API url.

  1. Restart the Agent to begin sending Elasticsearch metrics to Datadog.

Validation

Run the Agent’s info subcommand and look for elastic under the Checks section:

  Checks
  ======
    [...]

    elastic
    -------
      - instance #0 [OK]
      - Collected 118 metrics, 0 events & 2 service checks

    [...]

Compatibility

The Elasticsearch check is compatible with all major platforms.

Events

The Elasticsearch check emits an event to Datadog each time the overall status of your Elasticsearch cluster changes — red, yellow, or green.

Service checks

elasticsearch.cluster_health:

Returns OK if the cluster status is green, Warn if yellow, and Critical otherwise.

elasticsearch.can_connect:

Returns Critical if the Agent cannot connect to Elasticsearch to collect metrics.

Troubleshooting

Agent cannot connect

    elastic
    -------
      - instance #0 [ERROR]: "('Connection aborted.', error(111, 'Connection refused'))"
      - Collected 0 metrics, 0 events & 1 service check

Check that the url in elastic.yaml is correct.
